I have a 1995 dodge 4x4 with a 5.2, when i drive this truck for 20min and am going over 90k it starts runnig like it has bad gas or plug. If u stop it will idol rough and if u leave it for a bit it cleans up. but then it does this again and agian. if i shut it down for a bit it runs good again but for a limited time. Got any ideas what this would be? it does bring up a code 37 would this be my prob?

sound like a tork converter problem or the shift solinoids are faulty or internal damage have it scanned hope this helps

2 or 4 barrel?
If auto choke, chk yhat for opening.
Msnifold vac fluctuating or thats just the range? Sounds a little high. neck time you start the motor, give the throttle a snap and vck the coke play position Cold running the choke should be 1/4 - 1/3 open. If you need info on how to adjust let me know Hot, or at operating temp, choke should be wide open. Good luck.

Check the fuel pressure with a known good gauge - sounds like pump may be failing. Does it only run poorly if it's below 1/2 tank or all the time?

did u try turning the distributor??? if u did u need to take it to a shop and have the cam sync reset with a scanner,turning the distributor on those engines DOES NOT change timing.how many miles on this truck?? over time the dist. gear weares and it can also change the cam sync,also look at the little vacuum port on the passenger side of the intake manifold and see if the rubber plug or hose is missing off of it,also does this truck consume oil?? if it does it could also be your problem,a pan on the bottom of the intake manifold leaks and that could cause yur problem also,to test for that simply put your thumbs over the holes in the valve covers with it running..if it sucks yur thumbs in, that gasket needs to be replaced and it will also cut down or stop your oil use,hope this helps

code - 37 TCC brake switch circuit error. this is the torque converter clutch. Open or shorted condition detected in the torque converter part throttle unlock solenoid control circuit

• For turbocharged engines , code 37 will be triggered when the baro-read solenoid circuit is open or shorted.
• For normally aspirated (non turbo) engines with automatic transmissions, code 37 will be triggered when the Part Throttle Unlock (PTU) solenoid circuit is open or shorted.
• For normally aspirated cars with manual transmissions, code 37 is sometimes set for no apparent reason.

This is detected when the ECU doesn’t sense near 0vdc or 12vdc at the relay when the solenoid is turned on or off. When code 37 is thrown the power limited light will not be lit and the system will not enter limp mode.
